A pip is a standard unit used to describe a small change in the exchange rate of a currency pair. It helps traders measure price movement, spreads, potential profit and potential loss. Knowing the value of one pip before placing a trade is essential because it shows how much money may be gained or lost for each pip the price moves.
Pip value is not the same for every trade. It depends mainly on the currency pair, the lot size and the currency of the trading account. A position can move the same number of pips in two different pairs but create different monetary results.
What a pip means in forex
For most currency pairs, one pip is the fourth decimal place. A move from 1.2500 to 1.2501 is a move of one pip. A move from 1.2500 to 1.2510 is a move of ten pips.
Pairs that include the Japanese yen are usually quoted with two decimal places for a pip. For example, a move from 150.00 to 150.01 is one pip. This difference exists because the yen has a lower unit value than currencies such as the US dollar or euro.
Some trading charts show an extra decimal place. This smaller unit is often called a pipette, or one-tenth of a pip. A price change of one pipette is smaller than a full pip. Check whether a chart or order window is displaying pips or pipettes before calculating risk.
How lot size affects pip value
A lot size is the number of currency units represented by a trading position. In forex, the common reference sizes are:
- Standard lot: 100,000 units of the base currency.
- Mini lot: 10,000 units of the base currency.
- Micro lot: 1,000 units of the base currency.
The base currency is the first currency in a pair. In EUR/USD, the euro is the base currency and the US dollar is the quote currency. A 0.10 lot position is normally a mini lot, meaning 10,000 units of the base currency.
As position size increases, the monetary value of each pip increases in direct proportion. Doubling the lot size doubles the pip value. Reducing a position from 0.10 lots to 0.01 lots reduces its pip value to one-tenth. This is why position size should be chosen from the amount at risk, rather than from a desired profit target.
Calculating pip value for major pairs
For a pair where the account currency matches the quote currency, the calculation is straightforward. Use this formula:
Pip value = pip size × number of units traded
For most non-JPY pairs, the pip size is 0.0001. Imagine a $1,000 account trading a hypothetical 0.10 lot position in EUR/USD. The position size is 10,000 euros. If the account is denominated in US dollars, the arithmetic is:
- Pip size: 0.0001
- Position size: 10,000 units
- 0.0001 × 10,000 = 1
Therefore, one pip is worth $1 for that hypothetical 0.10 lot position. A movement of 25 pips would equal $25 before spreads, commissions, swaps and any other applicable trading costs. A movement of 25 pips in the opposite direction would create a $25 loss before those costs.
The same approach applies to other major pairs when the quote currency is also the account currency. For example, if a USD-denominated account trades a pair quoted in US dollars, the pip value can be calculated directly in dollars.
Calculating pip value for JPY pairs
JPY pairs use 0.01 as the pip size. With a hypothetical 0.10 lot position, the calculation begins in yen:
- Pip size: 0.01
- Position size: 10,000 units
- 0.01 × 10,000 = 100
One pip is therefore worth 100 yen for this hypothetical position. If the trading account is denominated in yen, the calculation is complete. If the account is denominated in another currency, the 100 yen amount must be converted into the account currency.
For a simple hypothetical conversion, assume 100 yen equals $1. Under that assumption, one pip would be worth $1 in a US dollar account. The actual converted value changes as exchange rates change, so a platform’s order window or position calculator may show a slightly different value from one moment to another.
When the account currency differs
When the quote currency does not match the account currency, calculate the pip value first in the quote currency, then convert it. For example, a pip value may first be expressed in euros, pounds or yen. It must then be translated into the account currency using the relevant exchange rate.
This is especially important for traders who hold accounts in Brazilian reais or another local currency. A trade may have a stable pip value in its quote currency, while its value in the account currency changes because of the conversion rate. Treat the displayed account-currency value as the figure used for risk planning.
Common pip value mistakes
- Using 0.0001 for a JPY pair instead of 0.01.
- Confusing a pipette with a full pip.
- Assuming 0.10 lots means the same cash risk across every pair.
- Ignoring the account currency conversion.
- Calculating only price movement while leaving out spreads, commissions and overnight financing costs.
- Choosing lot size before deciding how much of the account can be lost if the trade fails.
A practical check before trading
Before opening a position, write down the lot size, pip value, planned exit level and maximum acceptable loss. Multiply the number of pips between entry and the planned protective exit by the pip value, then add estimated trading costs. If the total risk is too large for the account, reduce the lot size or skip the trade. This calculation cannot remove market risk, but it makes the amount at risk clear before money is committed.
